So, I bought a Diavolino kit with all the bells and whistles last week, and just now got around to assembling it. Some of the shields I want to use need 3.3 volts, so I grabbed a spare LD33V regulator and hacked it in. I soldered wires to VIN (at the regulator bypass jumper), Ground (at the battery input), and 3V3 (at the 3V3-VCC jumper). The completed mod is below, and the full photoset (with notes) is over at http://www.flickr.com/photos/damurdock/sets/72157627228948638/.
